Open standard for user authentication
- FIDO2 (Fast IDentity Online 2) is an open standard for user authentication that aims to strengthen the way people sign in to online services to increase overall trust. FIDO2 strengthens security and protects individuals and organizations from cybercrimes by using phishing-resistant cryptographic credentials to validate user identities.

What is FIDO2? FIDO2 enables users to leverage common devices to easily authenticate to online services in both mobile and desktop environments. The FIDO2 specifications are the World Wide Web Consortium’s (W3C) Web Authentication (WebAuthn) specification and FIDO Alliance’s corresponding Client-to-Authenticator Protocol (CTAP).
FIDO (Fast IDentity Online) authentication is an authentication standard that uses public key cryptography to create a login experience that’s more secure, phishing-resistant and convenient than passwords. In the past, many online services relied solely on passwords for authentication.

FIDO stands for Fast Identity Online. With an added number two at the end, this acronym is based upon previous work done by the FIDO Alliance, particularly in terms of developing the Universal 2nd Factor (U2F) authentication standard. The FIDO Alliance was founded in July 2012 by PayPal, Lenovo, Nok Nok Labs, Validity Sensors, Infineon, and Agnitio...
The FIDO2 protocol uses public-key cryptographyto guarantee a secure and convenient authentication system. The FIDO2 standard uses a private and public passkey to validate each user’s identity to achieve this. To use FIDO2 authentication, you’ll have to sign up for it at FIDO2-supported services. So, how does this look in practice? Here’s a quick F...
So, how does FIDO2 affect the overall user experience through real-life examples? Even more important for the average user, in what form can you implement it in your day-to-day life? Let’s take a closer look at how you can implement FIDO2 passwordless login in different forms:
Now that we understand how FIDO2 authentication works, it’s also useful to do a FIDO2 vs. FIDO U2F comparison to determine the difference. The most significant difference between the two is that the former was created to allow all authentication to become passwordless. On the contrary, FIDO U2F was designed to serve as a second factor for passwords...
FIDO2 Advantages
The most significant advantage of FIDO2 authentication is that it creates a much smaller attack window for cybercriminals. To access your sensitive private information, attackers will need a FIDO2 authenticator, which is physically always by your side in the form of your device or your biometrics. If you use several FIDO2-supported sites, you’ll enjoy another advantage in the form of a more streamlined experience, as you won’t have to remember multiple login details and passwords for each of...
FIDO2 Disadvantages
Of course, like any other security method in the world, the FIDO2 standard does have certain disadvantages. These drawbacks aren’t deal-breakers but are something you should be aware of if you plan on implementing the FIDO2 passwordless login as a security practice. Most notably, this standard requires an additional security step compared to traditional password login standards if you use it as a regular component of two-factor authentication. With that in mind, such a system isn’t the most p...
Cyber-attacks have shown us that the human risk factor is a significant aspect of cybersecurity breaches. With FIDO2 implementation and passwordless authentication, the human risk factor is eliminated, allowing for a much safer user experience. FIDO2 implementation fits perfectly into a zero-trust security framework. Apart from being robust and com...
FIDO Authentication, developed by the FIDO Alliance, is a global authentication standard based on public key cryptography. FIDO Authentication provides a simpler user experience with phishing-resistant security.
May 24, 2024 · The FIDO2 passwordless authentication standard has revolutionized the cybersecurity landscape by eliminating the dependency on passwords and offering a robust, convenient, and foolproof alternative.
Sep 30, 2024 · What Is FIDO2? FIDO2 is the newest set of specifications from the FIDO Alliance. It enables the use of common devices to authenticate to online services on both mobile and desktop environments, using unique cryptographic login credentials for every site. Essentially, FIDO2 is passwordless authentication.
